Johnson took to Facebook late Wednesday night to respectfully call out the onetime former title challenger, arguing a fight between them is a matter of necessity.

Not to mention, he added, it has the seal of approval from UFC President Dana White.

“I respect you as a fighter but this is business,” he wrote. “@danawhite said our fight makes sense. There’s nobody left for us to fight plus the fans are begging for us to fight so let’s give the fans what they wanna see!”

Gustafsson remains unbooked after a knee injury forced him out of a title rematch with champ Jon Jones, who was subsequently booked to fight Daniel Cormier at UFC 178 and later rebooked for UFC 182 when he suffered a knee injury.

The UFC, however, saw it differently. In the wake of the Jones vs. Cormier postponement, White said earlier this month that a bout between Gustafsson and Johnson made sense.

Since Gustafsson regularly posts on his Facebook account, fans should know soon whether he agrees with White and Johnson, who’s shot into title contention after back-to-back wins, including a 44-second knockout of Antonio Rogerio Nogueira.

Gustafsson was in line to rematch Jones after a “Fight of the Year” candidate this past September at UFC 165. Jones took home a decision, but got pushed to his limit, and many, including White, talked up an immediate rematch.

Jones, however, skipped over Gustafsson in favor of an April fight with Glover Teixeira at UFC 172. After winning that bout decisively, he signed on for an ill-fated rematch.

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
